Aussie Broadband is upgrading its national and international network links for increased capacity.

The redesign includes 400Gbps backbone links between POPs (points of presence) within the same state, plus 200Gbps between Melbourne and Sydney, 100Gbps between Perth and Sydney, 100G between Perth and Melbourne, 40Gbps between Sydney and Brisbane, 20Gbps between Adelaide and Sydney, and 10G between Adelaide and Perth.

All these links run over diverse paths.

"We're also delighted to say that we will shortly complete protected 10G links to all NBN POIs other than Tasmania, with the final four links due in the next 30 days," said managing director Phillip Britt.

"This rollout has been a massive effort on behalf of all those involved – particularly our network team and our partners at Telstra Wholesale – but is starting to show strong benefits including a reduction in areas affected by our 80% stop-sell policy, and a reduced number of outages."

Under that stop-sell policy, Aussie Broadband does not take on a new customer unless it has at least 20% spare bandwidth at the relevant POI (point of interconnect).

International network improvements are also in train.

To date, Aussie Broadband has purchased IP transit capacity through Telstra Wholesale, said Britt, but "I'm really pleased to announce that we have purchased capacity on both legs of Southern Cross and the new Hawaiki Cable system to San Jose and Los Angeles. To match this, we will establish points of presence at Coresite SV1 in San Jose and Coresite One Wilshire in Los Angeles.

"We have also purchased capacity on the Vocus Australia Singapore Cable and will acquire capacity on Indigo West once available, again to be matched by a point of presence at Equinix SG1 in Singapore."

He added "The end goal is always improving the customer experience. Customers will enjoy an even better performance from their streaming services and gamers will notice a reduction in ping times."

The national and international network upgrades are scheduled for completion by the end of April.

In addition, Aussie Broadband has selected Cisco as its primary network equipment vendor, and will be using the ASR9K aggregation services routers and the Network Convergence System 5500.

The company recently connected its 100,000th customer, and now has more than 100,000 NBN services connected.

"This network upgrade will support our continued rapid growth," said Britt.

The upgrade will allow for easy scaling to 500,000 users, according to the company.
